Hi helper,

I install a CD changer myself, but nothing happen
from head unit, do I need to press any special
code to active the symphony cdc?
please someone help me!

....you should hear the motor working inside (at least this will tell you if the changer itself is working). Technically you shouldn't have to enter any code or anything in order for the changer to work. Just press the 'Mode' button and it should work.

have you fitted a changer with the symphony head?if so any problems with diy?also what changer did you fit? been trying to find someone who has done this for a while!many thanks tony.
